The alert is probably a false positive because of some of the various discussions (possibly about piracy and links to websites labeled as nefarious or something along those lines) that appear in any one of the thousands of posts in Everything Else. It's nothing to worry about. Probably partly your fault, somehow.

McAfee does that, its because less than 5 of their users have tried to visit this site according to my friend's comp. Just add an exception into the list of sites, I forget how, and you will be able to view the forums with no negatives.
